Hybrid L2s are a new class of L2s that inherit security from multiple L1s, e.g. Bitcoin and Ethereum. This makes them not only the most secure web3 platforms on the market, but also removes the need for 3rd party bridges: a hybrid L2 has native bridges to each of the connected chains. This means users from Bitcoin can always get their BTC back, same for ETH/ERC20 users from Ethereum, etc.
BOB is the first to introduce the hybrid L2 design in 2023. BOB uses BitVM2 to achieve Bitcoin security as a rollup, while creating native connections to Ethereum, and other L1s like Solana and Tron in the future. The release of the official BitVM2 technical paper, co-authored by BOB co-founder Alexei Zamyatin, is a major milestone in creating a new generation of web3-native platforms that can challenge centralized exchanges with never before seen security and UX. Tron and Starware recently followed BOB announcing their intentions to switch to hybrid designs to connect to Bitcoin - and more will follow.
Alexei Zamyatin is a co-founder of BOB (Build on Bitcoin), a first-of-its-kind hybrid Layer-2 powered by Bitcoin and Ethereum. Since 2015, he has worked on various Bitcoin-related topics, focusing primarily on security and interoperability, and in 2022, he earned a PhD in computer science from Imperial College London.
